The International Space Station Celebrates Its 10th Birthday

The International Space Station turns 10

This month marks the 10th anniversary of the first launched module of the International Space Station (ISS). The module Zarya was lifted into orbit on November 20th, 1998 by a Russian Proton rocket lifting off from Baikonur, Kazhakstan. In the decade since, 44 manned flights and 34 unmanned flights have carried further modules, solar arrays, support equipment, supplies and a total of 167 human beings from 15 countries to the ISS, and it still has a ways to go until it is done. Originally planned to be complete in 2003, the target date for completion is now 2011. Aside from time spent on construction, ISS crew members work on a good deal of research involving biology and physics in conditions of microgravity. If humans are ever to leave the Earth for extended periods, the ISS is designed to be the place where we will discover the best materials, procedures and safety measures to make it a reality.

In December 1998, the crew of Space Shuttle Mission STS-88 began construction of the International Space Station - Astronaut James Newman is seen here making final connections the U.S.-built Unity node to the Russian-built Zarya module. The crew carried a large-format IMAX camera from which this picture was taken. (NASA)

Backdropped against a blanket of heavy cloud cover, the Russian-built FGB, also called Zarya, approaches the Space Shuttle Endeavour and the U.S.-built Node 1, also called Unity (foreground) on December 6th, 1998. Inside Endeavour's cabin, the STS-88 crew readied the remote manipulator system (RMS) for Zarya capture as they awaited the rendezvous. (NASA) #

The Phantom Torso, seen here on May 13th, 2001 in the Destiny laboratory on the International Space Station (ISS), is designed to measure the effects of radiation on organs inside the body by using a torso that is similar to those used to train radiologists on Earth. The torso is equivalent in height and weight to an average adult male. It contains radiation detectors that will measure, in real-time, how much radiation the brain, thyroid, stomach, colon, and heart and lung area receive on a daily basis. The data will be used to determine how the body reacts to and shields its internal organs from radiation, which will be important for longer duration space flights. (NASA) #

How 10 Famous Technology Products Got Their Names

From iPod and BlackBerry to Twitter and Wikipedia, we take a look at the processes and people who came up with the names for these iconic tech products.

Coming up with a great technology product or service is only half the battle these days. Creating a name for said product that is at once cool but not too cool or exclusionary, marketable to both early adopters and a broader audience, and, of course, isn't already in use and protected by various trademarks and copyright laws is difficult—to say the least.

The makers of these 10 tech products—the iPod, BlackBerry, Firefox, Twitter, Windows 7, ThinkPad, Android, Wikipedia, Mac OS X and the "Big Cats," and Red Hat Linux—all have displayed certain amounts marketing savvy, common sense and fun-loving spirit in settling on their products' names. Here are the intriguing, surprising and sometimes predictable accounts of their creation.

iPod: "Open the pod bay door, Hal"

During Apple's MP3 player development, Steve Jobs spoke of Apple's strategy: the Mac as a hub to other gadgets. Vinnie Chieco, a freelance copywriter Apple hired to help name the gadget before its debut in 2001, fixed on that idea, according to Wired. He brainstormed hubs of all kinds, eventually coming to the concept of a spaceship. You could leave it, but you'd have to return to refuel. The stark plastic front of the prototype inspired the final connection: pod, a la 2001. Add an "i" and the connection to the iMac was complete.

BlackBerry: Sweet Addictiveness

Canada's Research in Motion called on Lexicon Branding to help name its new wireless e-mail device in 2001. The consultancy pushed RIM founders away from the word "e-mail," which research shows can raise blood pressure. Instead, they looked for a name that would evoke joy and somehow give feelings of peace. After someone made the connection that the small buttons on the device resembled a bunch of seeds, Lexicon's team (see profile) explored names like strawberry, melon and various vegetables before settling on blackberry—a word both pleasing and which evoked the black color of the device.

Firefox: Second Time's a Charm

Choosing a name that evokes a product's essence and is available can be quite complicated, as the Mozilla folks found out. The early version of Mozilla's browser was called Firebird, but due to another open-source project with the same name, the Mozilla elders renamed their browser Firefox, which is another name for red panda. Why? "It's easy to remember. It sounds good. It's unique. We like it," they said. Best of all? Nobody else was using it.

Twitter: Connecting the Digital Flock 140 Characters at a Time

When cofounder Biz Stone saw the application that Jack Dorsey created in 2006 he was reminded of the way birds communicate: "Short bursts of information...Everyone is chirping, having a good time." In response, Stone came up with "twttr," and the group eventually added some vowels. It's hard to think of a more evocative name in the tech world than twitter, but what began as what Stone described as "trivial" bursts of communication developed into a powerful means of networking, breaking news, and forum for the 44th U.S. president's campaign.

Windows 7: Counting on the Power of 7

While Microsoft's next OS is kind of a "Ho-hum" name, one has only to look at what happened with the most recent Windows release to understand why Microsoft might have gone back to a tried-and-true naming philosophy: Vista? Ouch. Windows 95 and XP? Those have done much better. Microsoft's Mike Nash announced the name this way: "Simply put, this is the seventh release of Windows, so therefore 'Windows 7' just makes sense." We're betting that Microsoft execs are hoping that number 7 will deliver on its promise of luck—they could sure use a win after Vista.

ThinkPad: Simplicity Wins Out

The venerable line of PC notebooks rolled onto the scene in 1992. While the concept was spot on, there was turmoil at IBM as to what to call it. IBM's pen-computing group wanted to keep it simple; they liked ThinkPad. But IBM's corporate naming committee didn't—it didn't have a number, and every IBM product had to have a number, and how would ThinkPad translate into other languages? Due to the chutzpah of the IBMer who unveiled it, ThinkPad won out, and it was a huge hit for IBM, which eventually sold it to Lenovo in 2005.

Android: Secretive, But Still Not Exciting

You'd think the story behind the naming of the Open Handset Alliance's new open-source platform for mobile devices, which includes the brand-new G1 loaded with Google's goodies, would be cool. But, uh, not so much. Back in 2005, Google quietly acquired a mysterious startup named Android Inc., which had been operating under "a cloak of secrecy" on "making software for mobile phones," reported Businessweek. The result of all Google's secrecy and Internet hype was the debut of T-Mobile's G1 on Oct. 22, 2008.

Wikipedia: Just What It Sounds Like

According to Wikipedia, the name Wikipedia is a portmanteau of wiki (a technology for creating collaborative websites) and encyclopedia (you remember, those large books that, as kids, we ruthlessly plagiarized for school book reports). FYI: a portmanteau is a fancy way of saying that we're going to take two words, jam them together and (hopefully) create a new concept that people will love. So far, so good. In an illustration of the axiom "the more things change the more they stay the same": Today, kids and adults now ruthlessly plagiarize Wikipedia instead of encyclopedias.

Mac OS X and "The Big Cats": Catlike Sleekness and Style

Apple's popular Mac operating system X actually denotes the Roman numeral 10, since it is the OS's tenth release, following Mac OS 9. To the ire of Apple fanboys, many people do refer to it as letter 'X.' More interesting have been the "big cat" code names assigned to each succeeding X release that have stuck with Apple's marketing: Cheetah (10.0), Puma, Jaguar, Panther, Tiger and current kitty Leopard. Snow Leopard has been assigned for the 10.6 release, with rumors that Lynx and Cougar are in the works.

Red Hat Linux: A Name Rich with Meaning

Cofounder Bob Young (pictured) has given multidimensional origins of the red fedora name:

1. It was named after red, which in Western history is "the symbol of liberation and challenge of authority." 2. Cofounder Marc Ewing wore his grandfather's red Cornell lacrosse hat in college and became known for this tech expertise—those with problems went to see the guy in the red hat. 3. Ewing named his software projects Red Hat 1, Red Hat 2 and so on. "So, when he started his Linux project, he just named it Red Hat Linux," Young said. All righty then!

ISS Astronauts Face Most Dangerous Challenge Ever: Home Remodeling

Astronauts prepare to give International Space Station extreme home makeover

By Daily Mail Reporter

The International Space Station is about to get all the comforts of a modern, high-end, 'green' home: a recycling water filter, kitchen fridge, extra bedrooms and workout equipment.

Space shuttle Endeavour's seven astronauts are due to carry the extra mod cons up to the station over the weekend.

They will convert the living area from a three-bedroom, one-bath, one-kitchen home to a five-bedroom, two-bath and two-kitchen home.

Changes to the International Space Station will enable it to home six astronauts instead of just three

NASA is already environmentally friendly, generating power through solar panels and recycling most waste.

But a new water recovery system will take this one step further, turning urine and condensation into fresh drinking water.

The system is essential if NASA is to increase the size of the space station crew from three to six by the middle of next year.

Endeavour's commander, Christopher Ferguson, said the water system would make deep-space exploration easier once crews are freed of lugging water.

'I would challenge you to find any other system on the Earth that recycles urine into drinkable water. It's such a repulsive concept that nobody would even broach it,' he said.

'But that day will come on this planet, too, where we're going to need to have these technologies in place, and this is just a great way to get started.'

The state of the art gym equipment and brand new toilet will be delivered over the weekend

The astronauts are also excited about getting their first kitchen fridge on board keeping their drinks cold and fruit fresher for long. The current lone refrigerator on board is restricted to science experiments.

'It seems kind of trivial, but six months of lukewarm orange juice can kind of bum you out,' said astronaut Sandra Magnus, who will fly up on Endeavour and move in for 14 weeks.

An exercise machine capable of some 30 routines will also be delivered.

NASA does not expect to get the water generation system up and running before spring. That's how long it will take to check everything and make sure the recycled water is safe to drink. Until then, the space station crew will continue to use water delivered by the shuttle and unmanned Russian supply ships.

Before Endeavour leaves, urine already collected by space station residents will be flushed through the system and undergo distillation, so recycled water samples can be returned to Earth for analysis.

Additional samples will be brought back by another shuttle in February to make absolutely certain the system is working properly.

If everything goes well, the space station will open its doors to six full-time residents next May or June.

The jump in crew size is especially important for the Canadian, European and Japanese astronauts who have been waiting years to live aboard the space station.

The larger, more diverse crew will boost the amount time spent on scientific research from 10 hours a week - the average now - to 35 hours a week, Suffredini said.

Most of the crew's time is now devoted to upkeep, and the maintenance chores will grow as the 10-year-old space station ages, he noted.

While fixing up the inside of the space station, Endeavour's astronauts will tackle a greasy, grimy job on the outside.

Three of the crew will take turns cleaning and lubricating a jammed solar-wing rotating joint; it's clogged with metal shavings from grinding parts and hasn't worked correctly for more than a year.

Toxic Melamine in 8 brands of powdered milk found positive in Bangladesh

BAEC find vindicates DU melamine results
Govt finally discloses to court 7 out of 8 milk powder brands tested positive; govt's role comes under criticism; court ruling today
By Ershad Kamol of “The Daily Star”


The government yesterday disclosed to the High Court (HC) that Bangladesh Atomic Energy Commission (BAEC) also had detected high concentration of toxic melamine in seven brands of powdered milk out of the eight tested so far.

The revelation raised questions among a cross-section of the people about the caretaker government's sincerity about ensuring public health as it had sat on the test results for a week instead of letting the worried consumers know about the findings.

The court is scheduled to pronounce a judgment on the melamine issue today.

On November 3 the government declared that melamine had been detected only in three Chinese powdered milk brands Yashili 1, Yashili 2, and Sweet Baby 2 in tests by a Thai and two local laboratories.

But at the time the government already had the BAEC test results in its hands which it decided to keep undisclosed.

The consumer confusion about melamine in powdered milk arose when about a month ago Health and Food Adviser Dr AMM Shawkat Ali opted to downplay a Dhaka University (DU) chemistry department test result that had detected melamine in eight brands of powdered milk including five popular ones.

Instead he and his government trusted the test results of the Bangladesh Standards and Testing Institution (BSTI), and of a private laboratory Plasma Plus, both of which detected melamine in only Yashili 1 while failing to find trace of the substance in the remaining seven brands.

Later the samples of all eight brands were sent to the laboratories of Bangladesh Council for Scientific and Industrial Research (BCSIR), BAEC, and a FAO recognised private laboratory in Thailand for testing.

This time around BAEC detected melamine in seven of the brands while the other two laboratories found contamination only in the Chinese brands.
The government adviser said on November 3 that BAEC and the DU chemistry department are not capable of conducting complicated tests like finding melamine in milk.

He told The Daily Star about the BAEC lab, "It's good for detecting pesticides and radiation levels, but not for detecting melamine in milk," adding that the DU chemistry department also has similar limitations.

Criticising the government's move to keep the BAEC test results hushed for a week, Transparency International Bangladesh (TIB) Chairman Prof Muzaffer Ahmad told The Daily Star yesterday, "It's a violation of the Right to Information Act which the government recently enacted. The persons responsible for hiding the information from the public should be put on trial according to the law."

"The government's role in such a complicated public health issue infers its lack of care for it. In fact, the government was hiding the facts for the welfare of the corrupt business community," he said.

Programme Officer of the Consumers Association of Bangladesh (CAB) Emdad Hossain said the way the government has been dealing with the melamine issue, is in violation of consumers' rights, because the consumers were kept in the dark about the confirmation of existence of a dangerously harmful substance in milk products they feed there children.

"People were in the dark and confused, as the government kept secret the test results. This is a blatant violation of consumers' rights, and very dangerous because of melamine's health implications," Hossain said.

The amounts of melamine detected by BAEC are 175.2 milligram per kilogram (mg/kg) in Yashili-1, 172 mg/kg in Yashili-2, 330.4 mg/kg in Sweet Baby-2, 171.3 mg/kg in Nido Fortified Instant, 478.3 mg/kg in Anlene, 287.4 mg/kg in Diploma, and 7.4 mg/kg in Dano Full Cream Milk.

However, BAEC did not detect any trace of melamine in Red Cow, which was found to be contaminated in the DU test.

Deputy Attorney General Rajik Al Jalil produced all test results to the HC yesterday, after the court had directed the government to do so.

Prof Nilufar Nahar, under whose leadership melamine was detected in the eight brands of powdered milk through a test in the DU chemistry department lab, said, "As a scientist I have a global reputation. The government should know my work before dismissing our department's abilities. I invite them to visit our laboratory and urge them to stop talking nonsense."

"The man who conducted the tests in Plasma Plus and the two others who tested the samples in BCSIR had been researchers under my supervision. I know the mistakes they made in their tests. The government should be ashamed of its blatant kowtowing to the interests of the unscrupulous industry, and for pitting novice chemists against the nation's top scientists."

She also questioned the authenticity of the test results from the Thai laboratory, saying, "It's a FAO recognised private laboratory, not FAO's own lab, moreover the report is incomplete." The report of the Thai lab did not elaborate on the methodology of its tests, she added.

"Local distributors of powdered milk brands should apologise to the public instead of trying to hide the facts, and at the same time they should ask the Chinese company Sanlu to compensate them for the loss of their business," she suggested.

Meanwhile, BSTI has been briefing the media on the 'safe level of melamine contamination', instead of warning the public about its disastrous impact on health, especially on children's health.

Four children died in China due to kidney stones that occurred from being fed melamine contaminated milk, while 53,000 others are currently suffering from kidney failures due to the same reason.
